If I take your brownie that's a brownie you can no longer sell or eat, this isn't the case when you copy software. If they stole a brownie you threw in the trash would you still call them a thief?
Either you can't see the moral argument, which leads me to believe you really are unable to see that piracy is theft. Or you simply don't want to see it and then I fall back to think this is motivated ignorance.
If you don't care to engage with the idea then I don't care to continue.
